SUMMARY:ClimaCore.jl: A New Flexible and User-Friendly Dynamical Core
DESCRIPTION:Minisymposium\n\nClimaCore.jl: A New Flexible and User-Friendl
 y Dynamical Core\n\nBarra, Byrne\n\nThe Climate Modeling Alliance (CliMA) 
 is developing a new Earth System Model (ESM), entirely written in the Juli
 a programming language. The CliMA model aims at targeting both CPU and GPU
  architectures, using a common codebase. ClimaCore.jl constitutes the open
 -source, light-weight dynamical core (<em>dycore</em>) of the atmosphere a
 nd land models, providing discretization tools to solve the governing equa
 tions of the ESM component models. ClimaCore.jl's high-level application p
 rogramming interface (API) facilitates modularity, composition of differen
 tial operators, definition of flexible discretizations and library reuse. 
 This, in turn, is coupled with low-level APIs that support different data 
 layouts, specialized implementations, and flexible models for threading, t
 o better face high-performance optimization, data storage, and scalability
  challenges on modern heterogeneous HPC architectures.<br />In this talk, 
 we will illustrate ClimaCore.jl’s conceptual framework and show its suppor
 t for nonlinear operator composition and library reuse with examples of ap
 plications that arise in idealized atmospheric dynamics, such as compressi
 ble fluid flows, shallow-water equations, and flux limiters for transport 
 problems.\n\nDomain: Climate, Weather and Earth Sciences, Computer Science
